YARN-SEPARATOR FOR SPINNING-MACHINESQ SPECIFICATION forming part ofLetters Patent N 0. 589,932, dated September 14:, 1897.

' Application filed March 12, 1896. Serial No. 582,975- (No model.)

.To aZZ whom it mag concern.-

.Be it known that I, ALFRED D. CHANDLER, a citizen of the United Statesof America, residing at Fall River, in the county of Bristol and Stateof Massachusetts, have invented a certain new and useful Improvement in-Yarn-Separators for Spinning-Machines, of

which the following is a description, reference being had to theaccompanying drawings, wherein- Figure 1 is a front view of a part of aringspinning frame showing portions necessary to illustrate saidimprovement. Fig. 2 is a sectional elevation on the plane denoted by thedotted line a: x of Fig. 1, lookingin the direction indicated by thearrow overlying that line. Fig. 3 is an end elevation view looking inthe opposite direction from that of Fig. 2. Fig. 4 is a sectionalelevation view showing the parts in adjustment for dofling My inventionrelates to yarn-separators for spinning-machines; and it consists in thedevices and combinations hereinafter described and claimed, the objectof said invention being to provide means to facilitate the removal ofthe separators from between the spindles and to hold the thread-board upand out of the way at the time of doffing or taking the full bobbins orcops from theirspindles; alsoin means for replacing said separators intheir operative position between the spindles after the empty bobbinshave been placed upon the spindles, and also means for actuating andvarying the limit of the traverse of the separators.

In the accompanying drawings the letter a denotes the frame of thespinning-machine, Z) 11 the bobbins upon two neighboring spindles, and cc the threads appurtenant to the cops of the same undergoing a-spinningoperation.

The letter (1 denotes the separators, whose office it'is to keep thesethreads apart in the spinning operation. They move up and down inpractically synchronous correspondence with the laying of the threads onthe cop, this motion being accomplish ed by a suitable connection fromthe builder shaft e, which has for that purpose a suitable reciprocatingrotary motion.

The letter f denotes an arm carried by the builder-shaft, and g aconnecting-rod extend ing upward therefrom and connected at its upperend to the arm h, fast on shaft 2', and by means of this connection thereciprocating rotary lllOlllOllOf the builder-shaftis communicated tothe shaft 2'. The connection of the rod g to the arms f and h is pivotaland adjustable.

The shaft 1' carries the rigid arms 70.

The letter Z denotes a separator-bar carrying the separators cl androtarily hung to the arms through the medium of pivot-pins borne bybrackets m. Left to themselves the weight of the separators cl wouldavail to partially rotate the separator-bar, so that the separatorswould drop down and away from their position between the bobbins, and itis this position that it is desired they shall as sume when the operatorremoves the bobbins or the cops from the spindles.

The letters n denote pawls in the nature of retainers, pivotallyattached to the arms 70, which normally hold the separator-bar in itsset position with the separators between the bobbins or spindles.

The letter 0 denotes a threadboard hinged to the roller-beam p. 1

The letter 1' denotes a swinging connection hung to the thread-board andloosely attached to the retainers n by means of the projection 72., theybeing of suitable length not to interfere with the reciprocating of theseparators.

hen the operator is ready to remove the bobbins or cops, he throws thethread-board upward. This action, through the medium of said swingingconnection, raises the retainers n, loosening their hold on theseparatorbar, which then under the weight of the sep arators dropsdownward and away, so that the separators pass from their operativeposition between the spindles, and now the whole field is free to permitthe operator to remove the bobbins.

The letter 5' denotes a drum on the separator-bar; t, a strap or thelike connected to the periphery thereof, and u an arm on thethread-board, to which the end of the strapt is attached. It is a resultof this construction that when the thread-board is thrown down again toits normal position the arm a,

strap t, and roll 8 carry the separator-bar back to the operativeposition and the retainers n automatically retake their hold thereof.The arm a, strap '6, and drum .9 also cooperate when the thread-board isthrown up and the sepa rator-bar is tripped to hold the thread-board inthat adjustment until the operator forces it downward.

The letter 1; denotes hangers extending downward from the roller-beam.

The letter to denotes curved or cranked arms adjustably attached to suchhangers, and by means thereof the position of the shaft t with the partsit carries can be adjusted both vertically and laterally.

I claim as my invention and desire to secure by Letters Patent 1. As animprovement in yarn-separators, the combination of the rotaryseparator-bar, carrying the separators, the retainers, coopcrating withthe separator-bar to prevent rotation, the hinged thread-board, and thetrip connection 9' between the thread-board and the retainer, wherebywhen the thread-board is raised the retainer is released and theseparator is allowed to revolve downward and backward by gravity,substantially as and for the purposes specified.

2. The combination of the rotary separatorbar, carrying the separators,the retainers, the thread-board, hinged to the roller-beam, the tripconnection between the thread-board and the retainer, the drum on theseparatorbar, and the connection between the said drum and thethread-board, whereby when ward and backward by gravity, substantiallyas and for the purposes specified.

4. Theroller-beamhavingthe thread-board hinged thereto, and supportingthe shaft 2', said shaft carrying arms 70, with retainers 1t pivotedthereto, in combination with rotary separator-bars carried on the arms70, separators d borne on the separator-bars, and the curved slottedconnection between the hinged thread-board and the retainers n, allsubstantially as and for the purpose specified.

5. The roller-beam having the thread-board hinged thereto and supportingthe shaft i carrying arms 70 with retainers n pivoted thereto, incombination with a rotary separator-bar carried on the arms 70,separators CZ borne on the separator-bar, a curved slotted connectionfixed to the hinged thread-board and loosely attached to the retainer 9%by means of projection 71, and drum 3, strap Z and curved arm a, formingan extensible connection between the hinged thread-board and the rotaryseparator-bar, all substantially as and for the purpose specified.

6. In combination, the rotatory separatorbar Z carrying separators d,pawl n hung on rotatory arm 70 and carrying projection a, the slot-tedconnecting-rod r and thread-board 0, all substantially as described andfor the purposes set forth.

7. In combination, the rotatory separatorbar Z carrying separators d,the drum .9, strap 1 arm a and thread-board 0, all substantially asdescribed and for the purposes set forth.

8. In combination, the builder-shaft 6, arm

f, rod g, arm h, shaft 'Z, and arms 70 carrying the separator-bar Z withits separators, all substantially as described and for the purposes setforth.
